WITH MY HAND STILL ON THE MEND FROM MY BATTLE WITH THE METAL LATH, ARTURO STEPS IN TO FINISH THE BRICK WINDOW SILLS ON THE OUTSIDE OF THE HOUSE. I LIKE THE LOOK OF THE BRICK SILLS, AND IT MAKES IT EASIER TO ACHIEVE A WATER TIGHT SEAL AT THIS CRITICAL AREA. WHEN WE SET THE WINDOWS INTO THE OPENING, IT'S TEMPTING TO JAMB THE WINDOW UP TIGHT TO THE BOTTOM OF THE WOOD HEADER ABOVE, BUT THEN WE DON'T HAVE A GAP THAT I CAN FILL WITH CAULK.

CAULK HAS THE ABILITY TO EXPAND AND CONTRACT WITH THE CHANGES IN WEATHER, BUT THERE NEEDS TO BE ENOUGH CAULK SO IT CAN EXPAND.

A BEAD OF CAULK THAT IS ONLY PAPER THIN WON'T HAVE ENOUGH MATERIAL TO EXPAND AT ALL, BUT WILL INSTEAD ACT LIKE GLUE.
